<h2>String Constraints (NUnit 2.4)</h2>

<p>String constraints perform tests that are specific to strings.
   The following string constraints are provided.
   
<table class="constraints">
<tr><th>Syntax Helpers</th><th>Constructor</th><th>Operation</th></tr>
<tr><td>Text.Contains( string )<br>Text.DoesNotContain( string )</td><td>SubstringConstraint( string )</td></td><td>tests for a substring</td></tr>
<tr><td>Text.StartsWith( string )<br>Text.DoesNotStartWith( string )</td><td>StartsWithConstraint( string )</td></td><td>tests for an initial string</td></tr>
<tr><td>Text.EndsWith( string )<br>Text.DoesNotEndWith( string )</td><td>EndsWithConstraint( string )</td></td><td>tests for an ending string</td></tr>
<tr><td>Text.Matches( string )<br>Text.DoesNotMatch( string )</td><td>RegexConstraint( string )</td></td><td>tests that a pattern is matched</td></tr>
</table>

<h4>Examples</h4>

<div class="code" style="width: 36em"><pre>
string phrase = "Make your tests fail before passing!"

Assert.That( phrase, Text.Contains( "tests fail" ) );
Assert.That( phrase, Text.Contains( "make" ).IgnoreCase );

Assert.That( phrase, Text.StartsWith( "Make" ) );
Assert.That( phrase, Text.Not.StartsWith( "Break" ) );
Assert.That( phrase, Text.DoesNotStartWith( "Break" ) );

Assert.That( phrase, Text.EndsWith( "!" ) );
Assert.That( phrase, Text.EndsWith( "PASSING!" ).IgnoreCase );

Assert.That( phrase, Text.Matches( "Make.*tests.*pass" ) );
Assert.That( phrase, Text.Not.Matches( "your.*passing.*tests" ) );
Assert.That( phrase, Text.DoesNotMatch( "your.*passing.*tests" ) );

// Using Inheritance
Expect( phrase, Contains( "make" ).IgnoreCase );
Expect( phrase, EndsWith( "!" ) );
Expect( phrase, Matches( "Make.*pass" ) );
